CONSULTATION DRAFT Haemorrhoids Haemorrhoid symptoms

6.2 Haemorrhoids
Haemorrhoid symptoms are common in pregnancy, particularly in the second and third trimesters.
Advice on avoiding constipation may assist women to prevent or lessen the effects of haemorrhoids.
Topical products can be used to ease continuing symptoms.
Haemorrhoids are enlarged, swollen veins around the anus that are characterised by anorectal
bleeding, painful bowel movements, anal pain and anal itching. While the mechanism is not clear, this
is thought to be a result of prolapse of the anal canal cushions, which play a role in maintaining
continence. Constipation (see Section 7.9 of Module I) is the major precipitating factor for
haemorrhoids. Pregnancy also facilitates development or exacerbation of haemorrhoids, due to
increased pressure in rectal veins caused by restriction of venous return by a woman’s enlarged uterus
(Avsar & Keskin 2010).
Incidence during pregnancy
Haemorrhoids that were present previously may become symptomatic for the first time in
pregnancy. Haemorrhoidal symptoms are most common in the second and third trimesters of
pregnancy and after birth (Avsar & Keskin 2010).
While estimates vary, it is thought that 25–35% of pregnant women are affected by haemorrhoids
(Staroselsky et al 2008; Abramowitz & Batallan 2003). One observational study found that 8% of pregnant
women (n=165) experienced thrombosed external haemorrhoids in the last 3 months of pregnancy
(Abramowitz et al 2002).
Pain with bowel movements, bleeding and itching are often the first signs and symptoms of
haemorrhoids. Diagnosis is made by examining the anus and anal canal, usually by inspection. Digital
rectal examination and endoscopy (sigmoidoscopy and colonoscopy) may also be used. It is
important to rule out more serious causes of bleeding (Avsar & Keskin 2010).
Discussing haemorrhoids
Summary of the evidence
Treatment during pregnancy aims mainly to relieve symptoms and control pain (Avsar & Keskin 2010).
Most evidence for the effectiveness of haemorrhoid treatments comes from studies of non-pregnant
patients. Given the overall lack of evidence, there is consensus in clinical reviews for conservative
management in pregnancy including avoiding constipation, dietary modification, dietary fibre
supplementation and stool softeners (Avsar & Keskin 2010; Dietrich et al 2008; Wald 2003).
Topical products with analgesics and anti-inflammatory effects provide short-term local relief of
symptoms. There is no evidence on the effectiveness or safety of creams used in pregnancy; however,
the small doses and limited systemic absorption mean that they are unlikely to harm the third trimester
infant (Starolesky et al 2008).
While surgical removal of haemorrhoids may be a consideration in extreme circumstances, surgery is
rarely an appropriate intervention for pregnant women as haemorrhoidal symptoms often resolve
spontaneously after the birth (Staroselsky et al 2008).
Consensus-based recommendation vii
Offer women who have haemorrhoids information about increasing dietary fibre. If clinical symptoms
remain, advise women that they can consider using standard haemorrhoid creams.

straining with bowel motions.
